+******************************************************************************
+**
+** This file implements a C-language subroutine that converts the content
+** of an SQLite database into UTF-8 text SQL statements that can be used
+** to exactly recreate the original database.
+**
+** A prototype of the implemented subroutine is this:
+**
+** int sqlite3_db_dump(
+** sqlite3 *db,
+** const char *zSchema,
+** const char *zTable,
+** void (*xCallback)(void*, const char*),
+** void *pArg
+** );
+**
+** The db parameter is the database connection. zSchema is the schema within
+** that database which is to be dumped. Usually the zSchema is "main" but
+** can also be "temp" or any ATTACH-ed database. If zTable is not NULL, then
+** only the content of that one table is dumped. If zTable is NULL, then all
+** tables are dumped.
+**
+** The generate text is passed to xCallback() in multiple calls. The second
+** argument to xCallback() is a copy of the pArg parameter. The first
+** argument is some of the output text that this routine generates. The
+** signature to xCallback() is designed to make it compatible with fputs().
+**
+** The sqlite3_db_dump() subroutine returns SQLITE_OK on success or some error
+** code if it encounters a problem.
+**
+** If this file is compiled with -DDBDUMP_STANDALONE then a "main()" routine
+** is included so that this routine becomes a command-line utility. The
+** command-line utility takes two or three arguments which are the name
+** of the database file, the schema, and optionally the table, forming the
+** first three arguments of a single call to the library routine.
